Full Changelog: v2.30.0...v2.31.0

API changes:

  • gf_vect_mul_base() function now returns an integer, matching the return type
    of gf_vect_mul() function (not a breaking change).

Igzip compression improvements:

  • Added compress/decompress with dictionary to perf test app.
  • Zlib header can be now created on the fly when starting the compression.
  • Added isal_zlib_hdr_init() function to initialize the zlib header to 0.

Zero-memory dectection improvements:

  • Optimized AVX implementation.
  • Added new AVX2 and AVX512 implementations.

Erasure coding improvements:

  • Added new AVX512 and AVX2 implementations using GFNI instructions.
  • Added new SVE implementation.

CRC improvements:

  • Added new CRC64 Rocksoft algorithm.
  • CRC x86 implementations optimized using ternary logic instructions and
    folding of bigger data on the last bytes.
  • CRC16 T10dif aarch64 implementation improved.
  • CRC aarch64 implementations optimized using XOR fusion feature.

Documentation:

  • Added function overview documentation page.
  • Added security file.

Performance apps:

  • Changed performance tests to warm by default.

Example apps:

  • Added CRC combine example crc_combine_example for multiple polynomials.

Resolved Issues

  • Fixed various compilation issues/warnings for different platforms.
  • Fixed documentation on xor/pq gen/check functions, with minimum
    number of vectors.
  • Fixed potential out-of-bounds read on Adler32 Neon implementation.
  • Fixed potential out-of-bounds read on gf_vect_mul Neon implementation.
  • Fixed x86 load/store instructions in erasure coding functions (aligned moves
    that should be unaligned).
  • Fixed memory leaks in unit tests.
